DOUGH-HOLDING MACHINE. I

, Applioatlon filed Bay 21,

To all 1/: dOI/b it 1n my concern:

Be it known that I, FRANK X. Lnurr nnnUn,n citizen of the United States, residing at Sidney, in the county of Shelby and State of Ohio, have invented certain 11 w and useful Improvements in Dough-Molding Machines, of \v-hich' the following s a specification.

The invention relates to certain improvements in dough machines.

The object of the present invention is to improve the construction of dough molding machines, and to provide a simple, practical and eilicient dough molding machine of strong, durable, and comparativel inexpensive construction, adapted to orm a lump of dough into a thin sheet and simultaneously cpel the gas therefrom, and then, without. .mble seaming or mashing the front edge of the sheet, coil the latter into n spiral roll, and finally through kneading and pressure, mold the roll into a loaf of the't-lesired size, without killing or punishing thedough through too great working or excessive pressure in the treatment of the same, so that the dough will rise in the pan and make a nice loaf of bread.

further object of the invention is to simplify and improve the construction of the. dough curling or ceiling mechanism, and to provide pmitively operative dou h curling devices adapted to engage first t c front edge of the thin sheet of dough and fold or curl the same back u on itself to start the coiling operation, a'nc then successively engage the curled portion of the dough and complete the coiling of the same in a manner closely analogous to hand coiling and with an accuracy and positiveness fully e ual to hand coiling.

Anot or object of the invention is to pro vide a molding or shaping box equipped with adjustable kneadin means constituting the bottom of the mofd box and tidal ted to produce the desired amount ofkneo. in

116M011 to suit th character of the dong and the requirements of the trade in var1 ons localities and on able also of entirely eliminating the knee ing action so that the loaf may e molded or shaped under pressure in a molding box presenting a smooth bottom to the dough.

Furthermore, the invention has for its ob ectto provide a dough molding. machine adapted to be readily opened to exipose and afford ready access to the feeding and the flpeot flcation of Letters Patent.

sheeting or pressure rolls for cleaning the same, adjusting means being also provided for properly spacing the rolls to produce the desired pressure u on the dough.

lVith these an; other objects in View, the invention consists in the construction and novel combination of mrts hereinafter fully described, illustrator in the accom panyiny drawings and pointed out in the it being understood that various changes in the form, proportion, size and minor details of construction, within'the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Fi are 1 is a side elevation of a doughmoldiiig machine constructed in accordance with this invention, the hinged frame section which carries the outer feedin and sheeting or pressure rolls being swung ownward.

Fig 2 is an end view showing the arrangement of the hopper, the feeding and sheeting or pressure rolls and the endless detail view, partly she in box.

Fig. 8 is a detail view of the loekin means for securing the bottom of the mol ing or shaping box in its adjustment.

Fig. 9 is a detail view of the lockin de vice for securing the hinged section 0 the frame in its closed position.

ig. 10 is a detail transversefsectional' view illustrating the manner of pivotally mounting the pressure board.

Like numerals of reference designate corresponding parts in all the figtiies of the drawings.

In the accompanying drawin s,.in which is illustrated the preferred em odiment of the invention, the main frame of the dough the construction of the adjustable bottom of the molding or is a detail transverse sectional molding machine is composed of spaced sides 1 connected by suitable transverse frame members and provided at one end with vertical columns 2 and having a hinged outer section 3 carrying the outer rolls hereinafter described and adapted to swing downwardly and outwardly to the open position illustrated in'Fig. l of the drawings to afford access to the dough feeding and sheeting or pressure rolls. This construction is particularly advanta cons as it will enable scrapersto be readi y employed in ing rolls which are mounted on transverse shafts 7 and 8 are preferably concave as shown and the sides 7 of the hopper are preferably tapered and extended downwardly between the upper portions of the feeding rolls and present curved side edges to the same as clearly illustrated in Fig. 4 of the drawings. The outer roll is shown flanged and receives the inner roll between its flanges, but the flanges may of course be omitted if desired.

The flattened dough, which moves down wardly between the feed rolls 5 and 6, is caught between inner and outer intermediate transverse pressure or sheeting rolls 9 and 10 mounted op transverse shafts 11. and 12, which are ournaled in suitable bearings of the columns 2 and the hinged frame section 3. The intermediate sheeting or pressure rolls 9 and 10 are of uniform diameter to present cylindrical surfaces to the sheet of dough, and the outer roll is shown flanged to receive the inner roll. The dough is formed into a thin sheet through the squeezing and rolling action of the said rolls 9 and 10 and the sheeting operation of the dough is completed by a pair of lower sheetingpr pressure rolls 13 and 14 mounted on transverse shafts'lo and 16 which are journaled respectively on the columns 2 and the hinged frame section 3. As the sheet of dough passes downward between the sheeting or pressure rolls, it is reduced inthickness and increased in width arid the rolls rogressively increase in width downwar to accommodate the increasingiwidth of the sheet of dough. The lower rails 13 and 14 are cylindrical and the outer roll 14 is flanged like the outer intermediate roll but the flanges are non-essentialand in practice the size and number of the rolls may be varied.

The hinged frame section 3 is mounted at its lower end at 17 on a transverse shaft 18 of an inner roll 19 of an endless traveling conveyor 20 and it is equipped at its upper end with adjusting screws 21, threadedinto lugs 22 of the frame section 3 and carrying.

lock nuts 23, and provided at their inner ends with engaging portions or heads 24, which a re adapted to engage the columns for limiting the closing movement of the hinged frame section 3 and the space between the inner and jnstment enables the rolls to be set the proper ed on one of 811th parts and en aging lugs 35 26 of the other of such parts. he catches, which have beveled heads to enable them to automatically engage the lugs 26, are provided with threaded shanks 27 and adjusting nuts 28 to enable them to be adjusted to suit the adjustment of the hinged section 3 through the adjusting screws. Various other means, however, may be provided for adjusting the rolls and for securing the hinged frame section 3 in its closed position,

and while the locking devices are shown mounted on the columns in the accompanying drawings, the parts may be reversed and the locking devices arranged'on the hinged frame section 3. a r

The 'frame is provided at opposite sides with buffers 29, arranged to receive and cushion the hinged section 3 when the same is swung downward to its open position The buffers 29 are provided with shanks 30, mounted in lugs 31 and havingdisposed on them coiled springs 32, which are interposed between the buffers 29 and the lugs 31. The buiiers 29'limit the downward swing of the frame section and support the same in its open position.

The traveling endless conveyor 20, which may be constructed of canvas or other, suitable materiahuextendsi longitudinally of .the

machine at an inclination and it passes around an outer transverse roll 33. The

sheet of dough from the lower-pressure or sheeting rolls 13 and 14 is delivered on to the upper flight of the endless conveyer and is advanced by the same to the curling and coiling mechanism which comprises a curL I mg device dd and a coiling device 55, located above a smooth inner extended end portion 36 of the bottom of the molding or shaping i box of the machine. The front curling device 34, which extends transversely of the machine, consists of a plate of sheet metal or other suitable material having its upper edge rolled'to form an eye 37 for therecep tion of a transverse pivot or pintle 38, which 1:10

ii i) hinges the front curling device at the front end of. the molding or shaping box. The lower edge of the curler 34 is bent forwardly at right angles to provide a dough engaging flange 39, and when the curler is not in engngemcnt with the dough it hangs in a vertical position with the said flange in close proximity to the endless conveyor and in the nth of the sheets of dough, and as a sheet 18 advenhed on the bottom of the molding or shaping box by the endless conveyer, the flan e engages the front edge of the sheet of ough, in a manner closely analogous to the fingers of the hand, and curls the cngaged edge of the sheet Qtkllyillg the edge of the dough upwardly and haokwardly over the advancing sheet in substantially the arc of a circle. In this curling operation the curler 34 swings freely upwardly in the direction of the movement of the sheet and when the curler 34 reaches substantially a horizontal position the flange operates to pull the. edgeof the dough back and turn it down on itself, making a perfect curl of the dough without mashing or double seaming. The curler 34 which automatically disengagcs itself and swings hack to its initial position. may he providcd at its back with a weight, when it is constructed of sheet metal but it may he made of any othcr suitable material. The coiling of the shout of dough into a spiral roll is complcti-d hy the coiling device 3:), consisting of a rectangular plat-e, hinged at 41 at one of its transverse edges to the inner end of the top wall or pressure board 42 of the molding or shaping box and arranged shove the extended inner end of the bottom of the molding box at a slight inclination with respect to tinsame and extending: upwardly in the diicction of the movement of the dough, so as to effect a positive engagcment with the some The coiling device is provided at its lower face with transverse ribs 43 shoal dered at their front edges and presenting:

a inclined lower faces and forming rclntivcly sharp transversely disposed dough engaging edges. The series oi ribs extend from tinhinged edgoto the front or Frcc edge of the coiling device and the coil of tiw ,hcct of dongh'passing-hcncath the coiling da-vicc its is successively cngagcd luv the transwrsc ribs and is in continuous engagement with the coiling device and the sheet of dough is positively and accurately coili-d in a mad ner similar to hand coiling hy the successiw engagement of the r ihs throughout the lower face of the coiling device.

The dough is subjected in passing under the coiling device to suflic'n-nt press-nreto render the engagement positive and tincoil ing device is ndjustahly supported in proper position relation to the bottom of the moldmg'box by an adjusting screw 44 piv-' oted at 45 to an ear 46 of the upper face of ,i it tho scctions the coiling device and extending upwardly therefrom and pasing throu h an opening 47 iii a transverse pivot 47 w iich is monnted in a fork or bifurcation 48 of an arm 48. The screw 44 is provided with an adjusting: nut 49 arranged upon the pivot 47* and adapted to be rotated to l'aisc and lower the coilin device for supporting the same at the desired elevation. The pivotal mounting of the screw -14 and the hinging of the lower end of the same to the coiling device relieves the screw of all strain incident to the adjustment of the said coiling device and enables it to accommodate itself to the adjustment of the said device. This constrnction provides a simple. practical and cfiicicnt means for adjusting the coiling de ice.

The bottom oflthe molding box is composcd of a plurality of fixcd sections 50 spaced apart to receive adjustable sections Bl movable upwardly and downwardly in the spaces 52. between the fixed sections 50 and connected by longitudinal lJfllS 53 so as to move in unison.
